Here is the overall problem I am seeing...
1) Doubletree is just that, Doubletree... The city will likely no pick them for good reason (not enough brand name).
2) AH's design is not released, but they do not have a hotel brand picked yet and the city I think would want to know who they would work with before picking them.
3) Garrison is in the same position as AH without a hotel name... Both AH and Garrison would likely have to change their hotel design, as the high end brand names design their hotels carefully.
4) The Hyatt deal is likely the winner because it is high end (ehh, debatable) and has a good design. I am weary however of "building in phases" because that usually means build one like planned then scale back the other...
